# - Find gmp

# Find the GNU Multiple Precision Arithmetic Library headers and libraries.

#

#  GMP_INCLUDE_DIRS   - where to find gmp.h etc.

#  GMPXX_INCLUDE_DIRS - where to find gmpxx.h etc.

#  GMP_LIBRARIES      - List of libraries when using gmp.

#  GMPXX_LIBRARIES    - List of libraries when using the C++ wrapper of gmp.

#  GMP_FOUND          - True if gmp found.

#  GMPXX_FOUND        - True if C++ wrapper of gmp found.
